Can you remove the up/down arrow keys on the MBP 16" 2019?

Is it possible to remove the up/down keys in particular?

I was having issues with the down-button where it sometimes wouldn’t press. I assumed something was stuck under the key, so I plucked it out. Now it doesn’t seem to want to go back to its place. I can get it into place on right side of the button, but the left remains loose and you can lift it up.

In trying to debug and figure out how the button’s placed, I also removed the up-arrow key and now I’m having the same issue with that button, except in reverse. The left side gets snapped into place but the right side of the button remains lose and you can lift it up and play with it

So my question is: Have I in fact broken the keys and are they not actually possible to remove? Or am I just doing this wrong? How do I snap them back into place? I’ve tried removing the white butterfly underneath and tried snapping it onto the button but I can’t get the butterfly to stick to the key on both sides, one of the sides just keep remaining lose

Any help would be incredibly appreciated

Tyvm in advance
